で行う無段変速機構４と、前記無段変速機８の出
力軸１５の正逆回転切換えを切換えギア１８の移
動で行う正逆回転切換機構５とを備えた走行作業
車の変速操作装置において、前記変速用リング１
４の移動を変速レバー２１の中立位置を挟む前後
移動で行う他、前記切換えギア１８の移動を前記
変速レバー２１の中立位置前後の移動で回動され
るカムプレート２６の回動で行うようにするとと
もに、このカムプレート２６が一定角度回動した
とき前記切換えギア１８の移動が行われるように
した走行作業車の変速操作装置。 A continuously variable transmission mechanism 4 that changes the speed of the continuously variable transmission 8 by moving a speed change ring 14, and a forward/reverse rotation switch that changes the forward/reverse rotation of the output shaft 15 of the continuously variable transmission 8 by moving a switching gear 18. In the speed change operation device for a traveling working vehicle, the speed change ring 1 is provided with a mechanism 5.
In addition to moving the shift lever 21 back and forth across the neutral position, the switching gear 18 is moved by rotating a cam plate 26 that is rotated by moving the shift lever 21 back and forth between the neutral position. In addition, when the cam plate 26 rotates by a certain angle, the switching gear 18 is moved.
